The Hopper Ducts mod is a great add-on to the already great Hoppers in Minecraft. It adds a new item that acts as a transport system connecting hoppers and chests across long distances. The great part about this mod is you can send items upwards with the use of ducts.
A good example for one of its uses would be during mining expeditions. Instead of setting up a bunch of chests in your mine for excess cobble, why not set up a hopper and ducts to your home base’s chest(s)?
This way you can have a single hopper connected to multiple chests for easy transportation of materials.
What’s even better is you can now sort items to separate chests using the grated hopper. With it you can designate which items can pass through the hopper and all others will not. Connected over several chests you can get organized with your items and streamline sorting automatically.
